I CAN'T WIN A SUPERBOWL RING! THE WORLD IS UNFAIR!
That line of thinking makes me sad for the human race.
It really comes down to whether you think favor is a super reward that should only be given out to the very best players, or is a common thing that everyone needs and should be accessible to everyone. I think favor is the purpose of the game. It isn't optional to me. It's not playing football without getting a super bowl ring. It's playing football and having the football taken away from you 6 minutes into the game. The football game is no longer playable without a football.
The entire favor system is moronic. If I save the mayor's daughter from a cave full of monsters he is not going to say when I return to town, "Thank you for saving my daughter, but the monsters were not as hard as they could have been, so I only like you 1/3rd as much as I would if they had been harder."
Every quest on every difficulty should reward full favor. The entire system of having partial favor rewards should be scrapped. If you complete a quest, you get the full favor for that quest because you completed the mission and accomplished the goal. The only thing that makes any sense at all as far as partial favor goes, is for doing the quest without doing the optionals. Getting Guard Jung's badge from The Kobold's New Ringleader can offer extra favor, but running on elite instead of normal should not.
